    - Map of rate of change (daily, weekly, monthly, yearly)
    - Yearly award ceremony for positive rate of change and absolute level.

    Fantastic project!
    Is there any correlation between sustainability map, poverty, violence, happiness maps?

  2. uncompress

    Hi. I downloaded the population density, V4 data. However, I have not been able to uncompress the files. I have tried in 2 different computers using different software. I do not know if I am doing something wrong

  3. have a more flexible way of searching the Map Gallery

    On the URL http://sedac.ciesin.columbia.edu/maps/gallery/search/10 I sought information about the United States, in connection with my present research. By page 7 I realized the maps are largely sorted alphabetically by geographical location. Since I aim to see what's available, it appears that I have to click "next" another five dozen times in order to possibly reach the maps for USA. Is there a shortcut?

    Murray, there is a “browse by location” at the bottom of the left column on the map gallery page. You can choose the US from there and that will limit the gallery to three pages. You can also search for “United States” at the top of the same column. If there is a specific map or data set you are interested in let us know and we can tell you what we have available.

    Cheers,

  4. GPWv3 link points to an alpha site

    Hi it's me Sneha :) I was visiting the GPW collections page and found a bug on http://sedac.ciesin.columbia.edu/data/collection/gpw-v4, towards the end of the last para on "To see the previous version of GPW, visit the GPWv3 data collection". The link to GPWv3 points to an alpha.sedac.ciesin page.

  5. Provide a sample request for WPS Population Estimation

    I am trying to execute the WPS but I'm not sure if the format of the xml that I'm providing is correct. A sample request would help me and other users to use the plugin more efficiently.

    Thanks

  6. Give step-by-step instructions on using your datasets

    There should be a guide on how to properly use the datasets ie how to open them, use the data in JSON format. I, as a new user, know not how to open .tiff files or how to get the data into a CSV or JSON format. Guidelines on this would be much appreciated. The dataset I have downloaded is the zip with population density for 2015 for e.g.
    Thanks!

  8. Use much higher resolution data avilable for Norway

    The GPW4 maps (e.g. http://beta.sedac.ciesin.columbia.edu/data/set/gpw-v4-population-density-adjusted-to-2015-unwpp-country-totals) uses lower resolution data sets for some countries than necessary. Nor example, it only goes down to municipality level in Norway, while 250 m resolution for that country is available here:
    https://www.ssb.no/natur-og-miljo/geodata
    It is distributed as a set of shapes (https://www.ssb.no/natur-og-miljo/_attachment/101145?_ts=13d3e62d7d0), and corresponding densities (https://www.ssb.no/natur-og-miljo/_attachment/260833?_ts=153847c0a78). I'm sure similar data is available for most other European countries.

  9. Fix Projection errors in Global Man-made Impervious Surface & Settlement Extent from Landsat

    I downloaded ( by hand) all of the tiles in GMIS in a geographic projection. When I examined the booundary tiles (01, and 60) it is clear that these were not projected properly from UTM and have longitude extents of 360 degrees.

  10. Map client – needs to point back to the source of the data

    Map client – needs to point back to the source of the data – e.g. through link that show where the basic data is coming from, or through citation information in legend or label. This would enable readers to get reference documentation as well as getting the source datasets. Also would be useful to be able to print out the map and map metadata.

  11. List data in one column instead of two

    The browse and faceted search performs great. My only thought is that it would be better to have the data listed in one column instead of two. Browse could be smaller on this page – then larger once you select your method of access (i.e., Website, download, maps, more….
